slope of a vertical line? undefined, or infinity.

thank you

The slope of a vertical line is undefined. This is because a vertical line is perfectly perpendicular to the horizontal axis and does not have any change in the y-coordinate for every unit change in the x-coordinate. As a result, the slope of a vertical line cannot be determined using the formula (change in y/change in x), as there is no change in x. The slope of any vertical line is considered undefined and is not represented by a specific numerical value such as -5, -2, 2, or 5.
